Banana Image Generation Skill

Generate images using Google's Gemini 2.0 Flash image generation model, running with Deno.

Quick Start

Generate an image from a text prompt:

deno run --allow-all scripts/generate-image.ts "A cat eating a nano-banana in a fancy restaurant"

Transform an existing image:

deno run --allow-all scripts/generate-image.ts "Make this cat wear a top hat" --input cat.png --output fancy-cat.png

Requirements

```
GOOGLE_API_KEY
```
environment variable must be set
Deno runtime

Script Usage

The

scripts/generate-image.ts

script supports:

Flag	Description
`<prompt>`	Text description of the image to generate (required)
`--input <path>`	Input image for image-to-image generation (optional)
`--output <path>`	Output path for generated image (default: `generated-image.png` )

Examples

Text-to-image:

deno run --allow-all scripts/generate-image.ts "A futuristic city at sunset"

Image-to-image with custom output:

deno run --allow-all scripts/generate-image.ts "Add a rainbow to the sky" --input landscape.jpg --output rainbow-landscape.png

Programmatic Usage

Import and use in Deno scripts:

import { generateImage } from "./scripts/generate-image.ts";

await generateImage({
  prompt: "A nano-banana floating in space",
  outputPath: "space-banana.png"
});

With input image:

await generateImage({
  prompt: "Make this banana purple",
  imagePath: "banana.png",
  outputPath: "purple-banana.png"
});
